AUGUSTE VAGNIERE, OF LOS ANGELES, CALIFORNIA.

ELECTRIC-ARC LAMP.

SPECIFICATION forming part of Letters Patent No. 436,814, dated September 23, 1890.'

i Application led January 28, 1890. Serial No. 338,427. (No model.)

T all whom it may concern..-

Be it known that I, AUGUSTE WAGNIERE, a citizen of Switzerland, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Electric Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to electric-arc lamps and it consists in various features and details hereinafter set forth and claimed.

In the drawings, Figure l is a perspective view of my improved lamp, a part of the casing and the two main helices being removed to show more clearly the remaining parts; Fig. 2, a face view of the same; Fig. 3, a sectional view of the same on the line 3 8 of Fig.

2; Figs. 4, 5, and 6, views illustrating certain details of construction, and Fig. 7 a diagrammatic view illustrating the course of the currents.

The frame or body of the lamp comprises an upper disk F, a lowerdisk G, an inclosing shell or casing H, connecting the disks, an elongated plate Z', upon which the parts F G H rest, and rods Z and Z3 connected to the ends of the plate Z', and serving the twofold purpose of suspending the lamp and convey ing the current into and out of the same. Rods A B, connected at their upperends with the plate Z', carry at their lower ends a base frame or plate XV", upon which latter is mounted the negative carbons ll and the globe, which latteris not shown. The rods A B and Z Z3, where they connect with the plate or frame Z' and "W4, are insulated therefrom, and it will also be noticed that the rod A is made hollow to receive the wire W5, which extends from the base-plate WV* to the suspending-rod Z3. The rod Z is electrically connected with asuitably-insulated binding-post a by means of a plate Y', while the rod ZS is similarly connected to a post 0 by a plate Y2.

5 indicates a key or switch suitably insu lated from the disk G, in which it is journaled, and adapted to be thrown into and out of con tact with a sliiring-arm b electrically connected with the post o, it being understood of course that the key or switch is in electrical. connecswitch be turned so as to make contact with e the spring-arm l) the current will pass from the arm Z through plate Y', post a, wire b',

switch 5, spring-arm l), post 0, plate Y2, and.

out through arm Z3.

E E designate apair of electroanagnets or helices, whose frames are electrically conneoted to the disk F, and A is the armature for the magnets carried by a lever l5, which in turn carries the yoke L L', supporting the arms XV' W2, Figs. l and l.

The arms l' Y W2 are perforated to receive the carbon-rods R R2, carrying the carbons X X, and are connected to the yoke by means of screws T' T2 and F' F2, as clearly shown in Fig. 4. The holes in the outer ends of the arms WV W2 are made larger than the carbonrods, so that when the arms rise the edges of the hole or opening will bite upon the rods and raise them, as is customary. It will also be observed that the holes or openings at the inner ends of the arms XV' XW are slightly larger than the screw-rods T' T2 which pass through them, the object of which is to permit the adjustment of the arms relatively to the armature-leverl, and thereby regulate or vary the distance between the carbons to extinguish the light, or for otherpurposes.

D designates what I term the cut-out coil or electro-niagnet/7 and C the armature-lever therefor, pivoted to a bracket N, insulated from the framework, the armature-lever being provided with an arm K, adapted to make contact with a plate or bracket J, connected with a suitably-insulated post or screw V in the top disk F. The plate J or its screw V is connected with the wire 2 by a wire 6.

X indicates a resistance-coil of any desired construction, which is connected by means of a wire S with the bracket N, and by means of a wire 8l with the binding-post 0, the coil X' being supported by rods E on the top of the disk F.

A wire 2 extends from the binding-post ato the helix E, and is connected to the frame of the helix, which latter, as before stated, is electrically connected with the framework of IOO the lamp.- A part of the current that enters by wire 2 is carried by a Wire 3 through the cut-out coil D and to the helix E', to the frame of which the wire is' electrically connected, the current being thereby conveyed through the coils E E D to the frame-work of the lamp.

In order to insure the ready passage of the current from the frame-Work to the carbonholders R R2, I employ fiat copper strips 4, which, as shown in Fig. 1, bear against the carbon-holdin g rods.

The energization of the coil D causes the armature-lever C to rock, and so long as the lamp burns regularly the armature Will be held in such position as to keep the arm'K out of.. contact with the plate or bracket J, and prevent the current from passing throughthe resistance-coil.

When the helices E E are energized,.their .armature -levers 15 are, rocked, and, acting through the yoke L L and arms W W, causes the carbons to be brought to proper position.

After the carbcns have thus been separated, v

the current Will pass through them and, down into the plate W4, and thence out of the lamp through Wire W5 and rod Z?.

- When for any reason the courseof the current, as just described, is interfered with,.the

bracket N, Wire 8, coilX, wire 81, tothebinding-post o and thence out of the lamp.

Having thus described my invention, what I claim isl. In combination with the main circuit 2 and the helix E, included inthe said circuit,

the cut-out coil D and helix E', included in 4o the branch 3 of the main circuit, a normallyopen circuit 6 8 81, a resistance-coil X', included in the said circuit, a circuit-closerJ K, included in the normally-open circuit, and an armature C for the cut-out coil D, carrying 45 the part K of the circuit-closer, all substantially as shown. 2. In an electric-arc lamp, the cut-out coil D, connected with the helices, substantially as shown and described, in combinationwith 5o the armature-lever C, a wire K, extending at F2, and carbon-rods R Ri,l passing through. 6o

the outer ends of the arms-W W2;
